PBINTERS CHASE.

To all whom t may concern Be it known that I, EDWARD JACKSON, a citizen of the United States, and a resident of the city of New York, Richmond Hill, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Printers Chase, of which the following is a full, clear, and exact de scription. Y

The object of the invention is to provide a new and improved printers chase arranged to hold securely the type suspended without danger of dropping out in handling the chase.

Another object is to permit of lling the chase completely with type and without requiring the use of quoins and other filling and locking furniture.

With these and other objects in view, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the'claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improved printers chase;

Fig. 2 is an enlarged cross section of the same on the line 2-2 of Fig. 1; and

Fig. 8 is a plan view of a pair of clamping bars with parts broken out.

The frame of the printers chase is of usual form and is provided with dividing bars 11 and 12 to divide the frame into individual sections each receiving set up type. The dividing bar 11 is provided at its ends with dovetail tongues 13 engaging correspondingly shaped grooves 14 formed in the inner faces of the end members 16 of the frame 10. The dividing bar 12 is provided at its ends with dovetail tongues 17 engag` ing correspondingly shaped grooves 18 formed in the inner faces of the side members 19 of the main frame 10. rlhe several pairs of grooves 18 are preferably provided for engagement by the tongues 17 of the bar 12 to permit of dividing the frame into differently sized sections. The dividing bars 11, 12 are halved and do not properly intersect.

In order to lock the set up type in any one of the sections of the chase as described, use is made of a pair of clamping bars 20, 21

connected with each other by screw rods 22 having right and left hand screw threads screwing in the bars 20 rand 21 to allow of moving the saine toward or from each other. Each ofthe screws 22 is provided with a head 23, preferably of polygonal shape, to permit the application of a wrench or similar tool for turning the screw rod 22 in either direction to move the bars 20 and 21 toward or from each other. The head 23 of each ofthe screwsV extends between the bars 20 and 21 and when the latter are moved u close to the faces of the heads 23 then the ends of the screw rods 22 are about flush with the outer faces of the bars 20 and 21, as will be readilyA understood by reference to Fig. 3. In order to support the clamping bars 2O and 21 on the chase, the side and end meinbers `19 and 16v of the main frame 10 are provided along the top at the inner edges with rabbets 25, and similar rabbets 26 are formed along the top on each side of each dividing bar 11 and 12, and on the said rabbets 25 and 26 are seated lugs 27 projecting integrally from the ends at the top of each clamping bar 20 and 21 to support the latter on the corresponding main frame member and the corresponding dividing bar 11 or 12. In case the dividing bars 11 and 12 are not used then a pair of clamping bars 2O and 21 of the required length may be used between the side members 19, 19 or the end members 16, 16, the lugs 27 then resting in the rabbets 25 of the said side or end members.

It will be noticed that when the chase frame is resting on a bed or other surface then the type can be readily clamped in position in any one of the sections by a pair of clamping bars 2O and 21, one of which rests against the corresponding frame member and the other is moved from this bar by turning the screws 22 against the type thus clamping the same in position. In case the type in any one of the sections is in two portions then use is made of clamping bars, 20 and 21 by placing the same between the two portions and turning the screw rods 22 to move the bars apart and thus lock the two portions of the type securelyl in place in the corresponding section of the printers chase.

It will also be noticed that when the print crs chase is lifted from its support the clamping bars 2O and 21 are supported by their lugs 27 on the corresponding member of the chase and hence the type clamped in place by the said bars 20 and 21 is not liable to drop out. Y

lt will further be noticed that by using the clamping bars 20 and 21 no other filling or locking furniture such as quoins and the like are required. When it is desired to unlock and remove the type the screw rods 22 are turned in the opposite direction to move the clamping bars 20 and 21 toward each other, that is,-ont of clamping engagement with the type to permit removal of the latter and of the bars 2O and 21.V

VHaving thus described my invention, l claim as new and desire to secure by Letters Patent Y l 1. A printers chase, comprising a rectangular frame having the inner faces of its members provided With rabbets and .dovetail grooves, dividing bars extending at right anglesto each other and having dovetail ends fitting in the grooves of the frame, the said bars having rabbets along their upper edges, and a pair of adjustable clamping bars each providedat its ends With lugs projecting from the top and of the same Width as the bar, said lugs being seated on the rabbets of the frame and dividing bars.

2. A printers chase, comprising a frame having the inner faces of its members provided With rabbets and grooves, dividing bars having their ends litting in the grooves of the frame and provided With rabbets` along their edges, and a pair of clamping bars, each provided at its ends with tongues of the Same Width as the bar, said tongues being seated on the rabbets, the clamping bars being provided With means Jfor adjusting them to and from each other.
